Remarks
- GEL PU SEALANT may be overpainted with water based paints, however due to the large number of paints and varnishes available we strongly suggest a compatibility test before application.
- Do not use in applications where continuous water immersion is possible
- GEL PU SEALANT has a good UV resistance but can discolor under extreme conditions or after very long UV exposure
- Discoloration due to chemicals, high temperatures, UV-radiation may occur. A change in color does not affect the technical properties of the product
- Contact with bitumen, tar or other plasticizer releasing materials such as EPDM, neoprene, butyl, etc. is to be avoided since it can give rise to discoloration and loss of adhesion
- Not suitable for food contact applications.
